The fastest way to remove mold from clothes
The method depends on how much mold is present and what the fabric can handle. For light surface mold on sturdy fabrics like cotton or denim, brush the mold off outdoors with a stiff brush—this removes spores before they set deeper into the fibers. For heavier mold or delicate fabrics, soak the garment in white vinegar (undiluted) for one hour, then wash it in the hottest water the fabric label allows with regular detergent. Sunlight and heat kill mold, so dry the clothes outside in direct sun rather than in a dryer or indoors.
If vinegar alone does not work, a second wash with a mold-killing additive like borax (half cup per load) or hydrogen peroxide (one cup per load) will finish the job. Do not mix bleach with vinegar or ammonia—this creates toxic gas. Test any solution on a hidden seam first if the fabric is colored, because vinegar and hydrogen peroxide can lighten dyes.
Key Takeaways
- Always brush or shake mold off outside to avoid spreading spores indoors, and wear a mask if the mold patch is large.
- White vinegar works on most fabrics and colors without damaging them the way bleach can, though it may lighten some dyes.
- Wash in the hottest water the fabric label permits, because heat kills mold spores that detergent alone may miss.
- Dry clothes in direct sunlight outdoors whenever possible, since UV light and heat are the most reliable mold killers.
- If mold has penetrated deep into the fabric or covers more than a few inches, the garment may not be worth saving.
Brush off surface mold before washing
Take the moldy garment outside and use a stiff brush—an old toothbrush works for small areas, a clothes brush for larger ones—to scrub away the visible mold. Brush in one direction, away from your body, so spores fall to the ground rather than toward your face. If the mold covers a large area or you have mold sensitivity, wear a dust mask while brushing.
This step removes the bulk of the mold before it enters your washing machine, which matters because mold spores can spread to other clothes in the same load. Brushing also helps you see how deep the mold has gone—if it brushes away completely, the mold is only on the surface and will wash out easily. If dark stains remain after brushing, the mold has begun to eat into the fibers and will need soaking.
Soak in vinegar or hydrogen peroxide
Fill a bucket or sink with enough white vinegar to submerge the garment. White vinegar is safe on most fabrics and colors because it is mild—it kills mold without the bleaching power of chlorine bleach. Submerge the moldy clothing completely and let it soak for one to two hours. For very stubborn mold, leave it overnight.
Hydrogen peroxide (the 3 percent kind sold in drugstores) works similarly and may be gentler on delicate fabrics. Soak for 30 minutes to one hour. Do not use both vinegar and hydrogen peroxide in the same soak—they work differently and mixing them does not improve results. After soaking, rinse the garment in cool water to remove the vinegar or peroxide smell, then proceed to washing.
Wash in hot water with detergent
Check the fabric care label and use the hottest water temperature it allows. Hot water kills mold spores that soaking alone may have missed. Add your regular laundry detergent and wash the garment on a normal cycle. If you want extra mold-killing power, add half a cup of borax or one cup of white vinegar to the wash water along with detergent.
Do not overload the washing machine—mold-covered clothes need room to move so the water and detergent reach all surfaces. Wash moldy items separately from other clothes to avoid spreading spores. If your washing machine itself smells musty, run an empty hot cycle with two cups of white vinegar before washing the moldy garment, so you are not recontaminating clean clothes.
Dry in direct sunlight
Hang the wet garment outside in direct sunlight rather than using a clothes dryer or drying indoors. Sunlight and heat together kill any remaining mold spores and prevent new mold from growing as the fabric dries. Leave the garment in the sun for at least four to six hours, or until completely dry. If you live in a humid climate or it is cloudy, leave it out longer—the goal is complete dryness, not just surface dryness.
If outdoor drying is not possible, use a clothes dryer on high heat for at least 45 minutes. Heat alone is less effective than sunlight plus heat, but it still kills most mold. Do not hang the garment indoors to air-dry, because slow drying in a damp indoor environment can allow mold to regrow before the fabric is fully dry.
When to throw the garment away
If mold has spread across more than a quarter of the garment, or if it has penetrated deep into thick fabrics like wool sweaters or upholstered items, the garment may not be worth the effort. Mold that has eaten into fibers for weeks or months leaves permanent damage and discoloration that washing cannot fix. A musty smell that remains after washing and drying is a sign the mold has gone too deep.
Delicate fabrics like silk, lace, or vintage clothing are also risky to treat at home because vinegar and heat can damage them. If you are uncertain whether a garment is worth saving, consider the cost of replacement versus the risk of damaging it further. Throwing away heavily molded items is sometimes the safest choice, especially if anyone in your home has mold allergies or respiratory sensitivity.
Prevent mold from returning to stored clothes
Store clean, completely dry clothes in a cool, dry place with good air circulation. Use breathable storage containers like cotton bags or cardboard boxes rather than plastic bins, which trap moisture. Add a desiccant like silica gel packets or a small bowl of baking soda to absorb humidity inside the storage space. Replace baking soda every three months.
Keep the storage area between 50 and 70 percent humidity if you can measure it—a cheap humidity meter costs five to ten dollars. If you live in a very humid climate, run a dehumidifier in the closet or storage room during warm months. Check stored clothes every few weeks, especially in spring and summer when humidity rises. If you notice a musty smell, open the storage area to air and sunlight when ready.
Frequently Asked Questions
Can I use bleach to kill mold on colored clothes?
Bleach kills mold but will lighten or remove color from most fabrics. Use bleach only on white cotton or linen that you do not mind if it yellows slightly. For colored clothes, stick with white vinegar or hydrogen peroxide, which kill mold without bleaching. If you must use bleach, dilute it to one part bleach per ten parts water and test it on a hidden seam first.
How long does it take to remove mold from clothes?
Surface mold takes one to two hours of soaking plus one wash cycle, so roughly three to four hours total. Deeper mold may need overnight soaking plus two wash cycles, which takes 24 to 48 hours. Drying in sunlight adds four to six hours. The entire process from start to finish is usually one to two days.
Will mold come back if I wash and dry the clothes?
No, if the clothes are completely dry and stored in a dry place. Mold needs moisture to grow, so clothes that are fully dried and kept in a space below 70 percent humidity will not develop mold again. If mold returns quickly, the storage area itself is too damp and needs a dehumidifier or better ventilation.
Is it safe to wear clothes that had mold on them?
Yes, once they have been washed and dried completely. Mold spores are killed by heat and detergent, so wearing the garment poses no health risk. However, if you have mold allergies or asthma, you may want to wash the garment twice to be certain all spores are gone, or choose not to wear it if the mold was extensive.
What if the mold smell stays after washing?
A lingering musty smell means some mold spores or mold byproducts remain. Wash the garment again with vinegar or borax, then dry it in direct sunlight for a full day. If the smell persists after a second wash and sun-dry, the mold has likely damaged the fabric permanently and the garment may not be salvageable.
